Will iOS 7 finally make traditional PCs irrelevant?

Solution: "As CPU, memory and storage levels increase, these issues should diminish but there are clearly some aspects of these that are OS-dependent."

Other changes that would give iOS 7 the heft to deal with more complex tasks include:

a more granular iCloud backup, so you don't need to restore your entire device to recover one file

some kind of simpler, sane password management system

improved iOS virtual keyboard with, among other changes, more predictable autocorrect and a "text selection interface" that uses something other than the required "tap-and-hold" interaction

"wrist protection APIs," meaning a standard mechanism that digital ink, drawing, art, PDF annotators and other apps can use so that resting your wrists on the screen isn't confused with a gesture

abolishing the current 50MB limit that some Apple apps apply to cellular downloads

letting users select and set their own default apps, starting with email and browsing

Speirs argues that this "conceptually small set of changes," rather than a "ground-up rethink" or changes to make iOS "more like our existing desktop OSes," is what's needed "to satisfy more of the needs of the power user."
